Coupled Cycling of Dissolved Organic Nitrogen and Carbon in a Forest Stream
Dissolved organic nitrogen (DON) is an abundant but poorly understood pool of N in many ecosystems. We assessed DON cycling in a N-limited headwater forest stream via whole-ecosystem additions of dissolved inorganic nitrogen (DIN) and labile dissolved organic matter (DOM), hydrologic transport and biogeochemical modeling, and laboratory experiments with native sediments. We sampled surface and ...

متن کاملChanges in the character of stream water dissolved organic carbon during flushing in three small watersheds, Oregon
[1] The hydrologic and biogeochemical responses of forested watersheds to inputs of rainfall and snowmelt can be an indicator of internal watershed function. In this study, we assess how the quantity and quality, both chemical and spectroscopic, of stream water DOC changes in response to a 6-day storm event during the wet season of 2003 in three small (<1 km) basins in the H. J. Andrews Experim...
متن کاملUsing Dissolved Organic Matter Fluorescence to Signal Changes in Carbon Cycling During a Cave Stream Experiment
Cover Photo: Cave salamanders (Eurycea lucifuga) are often found in the "twilight zone " area. This zone is near the entrance of the cave where a small amount of natural light still falls. E. lucifuga feed mainly on various insects and spiders. In the fall one might find their eggs in little crevices of rocks that have water/moisture in them or along rimstone pools. This particular specimen was...
متن کاملCan the heterogeneity in stream dissolved organic carbon be explained by contributing landscape elements?
The controls on stream dissolved organic carbon (DOC) concentrations were investigated in a 68 km2 catchment by applying a landscape-mixing model to test if downstream concentrations could be predicted from contributing landscape elements. The landscape-mixing model reproduced the DOC concentration well throughout the stream network during times of high and intermediate discharge. The landscape...
